Abstract
The present invention provides a process for regenerating a deactivated heteropolymolybdophosphoric acid catalyst, comprising the steps of grinding the deactivated catalyst into particles having a particle size of 40 mesh or less, mixing the particles with a mixture comprising aqua ammonia, an aqueous solution containing ammonium ions and organic auxiliaries, kneading the same in a kneader to obtain a paste, drying the paste, molding the paste into cylindrical particles with a through hole in its longitudinal axis, and heating the paste in atmosphere at 350˜450° C. for 1˜10 hours to produce the generated catalyst.
